That is a logical and robust route to pursue. You won't waste much money with that plan.
Nathan Foster is the man who literally wrote the book on long range shooting, have a read through his website.

Have a read through some of the articles in the 'knowledgebase' tab of his website. If you like his writing style, you can't go wrong with buying one or all of his books, 'The practical guide to long range shooting' is a good start. I would suggest to anyone to read the book before spending any other money on long range stuff.
